Wireless Systems: Frequencies, Basic Issues & Solutions

Improve Performance with Tips from This 6-Chapter Series

Have you ever run a radio station? Basically that’s what you’re doing every time you operate a wireless system: A transmitter sends out a signal that is picked up by a receiver, albeit within a limited range and at low power.

A wireless microphone has an antenna that transmits radio signals to a receiver with an antenna, and that signal is sent by cable to a sound system. When you throw an in-ear monitor (IEM) into the mix, the IEM is the receiver being fed by a transmitter.

It’s a direct, fairly simple system, but problems can occur. “The Essentials of Wireless Systems”, Chapter 1 of 6 in the Expert Series on Wireless Systems addresses:

• How to reduce noise interference
• Why having equipment with more frequencies is important
• Where to find a list of TV channels to avoid
• What the sale of the 600 spectrum means
• What options you have for equipment in the 600-band range
• What alternate RF bands are available
• How to avoid “fizzing,” “swishing,” dropout and multipath
